DETACHABLE PLOW-POINT.

SPECIFICATION forming part of Letters Patent No. 704,996, dated July 15,1902.

Application filed April 30, 1901.

To all? whom it may concern:

Be it known that 1, CHARLES A. WEIMER, a citizen of the United States,residing at Carrollton, in the county of Greene and State of. Illinois,have invented a new and useful Improvement in Detachable Plow-Points, ofwhich the followingis a specification.

My invention relates to an improvement in my detachable plow-point onwhich Letters Patent No. 668,000 were granted to me February 12, 1901,the object being to provide a plow-point having the same advantages asmy former plow-point, with the additional advantage of being able toconstruct same out of steel at a nominal cost. This improvement isobtained not only in the change made in the aforementionedplow-point,but also in a corresponding change made in the plow'share towhich the plow-point is fastened.

While it is possible to make my improved plow-point of steel at a smallcost owing to its simple way of construction,it is not my intention toconvey the impression that it cannot be made of any other material usedin the construction of plows and their parts. The plowshare, also, inorder to have the effect of absolutely preventing vertical and side playis made in such a way as to be applicable to any ordinarymoldboard-plow.

My invention therefore consists incertain absolutely new features ofconstruction and combinations of parts, which will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a bottom perspective Viewshowing the point constructed and adapted to apply directly to theplowshare especially constructed for the purpose. Fig. 2 is a top viewofa plowshare constructed to receive my improved plowpoint. Fig. 8represents a side an d partial top view of my improved plow-point, andFig. 4 shows a plowshare with my improved plowpoint, adapted to give ageneral idea of how the plow-point is used.

A represents my improved p1ow-point. It is provided with a flat plateportion d, adapted to rest upon the plowshare, (shown in Fig.'2,) itoccupying the position indicated therein in dotted lines. The plow-pointis provided with a heel c, which has a triangular opening K formedtherein, and this triangular opening is constructed and adapted SerialNo. 58,194. (No model.)

to receive the forward end on of the landside M of the plowshare, whichlatter is shaped and cut to fit the opening as K, as shown in Fig. 4.The object of this arrangementis to prevent up and down or vertical playof the plow-pointwith respect to the other portions of the plow. Theplowshare, as shown in Fig. 2, has a notch F, whose sides a and E fitagainst the heel c, the plow-point and the side E fitting into notch Kand side a against heel c, Where the heel and plate 01 form an angle.Holes 1) b are formed in the flat portion of plate (Z of the plow-point,and the corresponding holes 9 gin the plowshare receive bolts 71 h,which secure the'plow-point in position. These fastening means-namely,the notch F, fitting into the end-and side of heel c, the recess K,receiving the projection m, and bolts h hconstitute an effectual andperfect fastening for the plow-point, at the same time requiringaminimum of time and trouble in the application and adjustment or removalof the point from the plow. By means of the several fastenings the pointis held in a perfectly rigid and fixed position with relation to themoldboard N and landside M, from which it cannot move except as the bolth itself is loosened and taken'from the holes I) b and g g. In thismanner a simple, inexpensive, and most efiectual steel plow-point isprovided.

Itis evident that slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of my invention, and hence I do not wish to limitmyself to the exactconstruction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A plow-point having a fiat portion or plate with the heel forming theonly elevation thereon, a plowshare with a special-shaped notch at theforward corner to fit against the heel and plate of the point to preventlateral or side play, said plow-point also'provided with a triangularopening formed by the j uncture of the plate and heelof the point toreceive a corresponding projection on the landside of the plow wherebyto prevent vertical play of the plow-point.

2. The combination with a plowshare having a notch of special shape inits forward ICO corner and a landside having a projection in its forwardedge, of a plow-point having a perfectly fiat lower surface providedwith a heel adapted to receive the notch of the plowshare and Whosetriangular notch formed by the juncture of the heel and plate is adaptedto receive and fit the projection on the forward edge of the landside,said plow share and point having holes therein and bolts adapted to passthrough said holes thereby to secure the plow- 10 point in position andcomplete the fastening.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses. 1
